Description

Double-layer wrecker with four lifting devices

Technical Field

The utility model relates to the field of flat-bed transport vehicles, in particular to a double-layer wrecker with four lifting devices.

Background

At present, only one obstacle removing vehicle can be pulled in many obstacle removing vehicles, and some obstacle removing vehicles can pull two obstacle removing vehicles, but the vehicles on the obstacle removing vehicles shake too much, so that the obstacle removing vehicles are unsafe, and the service life of the adopted lifting mechanism is not long.

Disclosure of Invention

The utility model aims to provide a double-layer wrecker with four lifting devices. The oil cylinders of the four lifting devices are matched with chains, so that the problems can be completely solved.

The utility model is realized in this way, a double-deck wrecker with four lifting gears, its characteristic is to mount winch, hydraulic tank, flexible ladder stand, bracket and lifting gear fixedly on the chassis, the wire rope is equipped with on the winch, winch and wire rope are in order to draw the obstacle car to the bracket; the tail part of the bracket is connected with a telescopic ladder stand; the four lifting devices are distributed on the front two and the rear two of the chassis, and mainly used for lifting the tray; the oil cylinder is fixed on the frame through an oil cylinder fixing seat, a piston rod of the oil cylinder is connected with a gear connecting seat, and the moving gear is arranged on the gear connecting seat; the chain fixing seat is fixed on the frame, and the chain connecting bolt is fixed on the chain fixing seat through a chain adjusting nut and a chain locking nut; the lifting seat is fixed on the lifting tray, the lower end of the chain is connected with the lifting seat, the other end of the chain is connected with a chain connecting bolt around the fixed gear and the movable gear, and the fixed gear is arranged on the fixed shaft.

Due to the adoption of the technical scheme, the method is convenient, quick, simple, safe and practical.

Fig. 1 is a schematic front view of the present invention.

Fig. 2 is a schematic view of the lifting device of the present invention.

In the figure: 1. a chassis; 2. a winch; 3. a wire rope; 4. a hydraulic oil tank; 5. a lifting device; 6. a bracket; 7. a tray; 8. a telescopic ladder stand; 9. a chain; 10. a moving gear; 11. a gear connecting base; 12. a piston rod; 13. an oil cylinder fixing seat; 14. a chain connecting bolt; 15. a chain adjusting nut; 16. a chain fixing seat; 17. a chain lock nut; 18. fixing a gear; 19. a fixed shaft; 20. an oil cylinder; 21. and (5) pulling up the seat.

Detailed Description

The utility model is further illustrated by the following examples and figures.

In fig. 1 and 2, a winch 2, a hydraulic oil tank 4, a telescopic ladder 8, a bracket 6 and a lifting device 5 are fixedly arranged on a chassis 1, a steel wire rope 3 is arranged on the winch 2, and the winch 2 and the steel wire rope 3 are used for dragging an obstacle vehicle onto the bracket 6; the tail part of the bracket 6 is connected with a telescopic ladder stand 8; the four lifting devices 5 are distributed on the chassis 1, the front two lifting devices are distributed on the chassis 1, the rear two lifting devices are distributed on the chassis 1, and the four lifting devices 5 are mainly used for lifting the tray 7 to ascend; the oil cylinder 20 is fixed on the frame through an oil cylinder fixing seat 13, a piston rod 12 of the oil cylinder 20 is connected with a gear connecting seat 11, and the movable gear 10 is arranged on the gear connecting seat 11; the chain fixing seat 16 is fixed on the frame, and the chain connecting bolt 14 is fixed on the chain fixing seat 16 through a chain adjusting nut 15 and a chain locking nut 17; the lifting seat 21 is fixed on the lifting tray 7, the lower end of the chain 9 is connected with the lifting seat 21, the other end of the chain 9 is connected with the chain connecting bolt 14 around the fixed gear 18 and the moving gear 10, and the fixed gear 18 is arranged on the fixed shaft 19.

The operation process is as follows: when the wrecker arrives at the site, the wrecker is firstly aligned with the wrecker, the wrecker is pulled to the tray 7 by using the winch 2, the steel wire rope 3 and the telescopic ladder 8, the cylinder 20 is given instructions after the front, the back, the left and the right are fixed, because the oil cylinder 20 is fixed by the oil cylinder fixing seat 13, the piston rod 12 of the oil cylinder 20 moves downwards, the piston rod 12 drives the gear connecting seat 11 and the moving gear 10 to move downwards, at this time, the chain 9 prevents the moving gear 10 from moving, because one end of the chain 9 is fixed on the chain fixing seat 16 and can not move, the other end of the chain 9 is fixed on the tray 7 by the pulling seat 21, the tray 7 is a whole body which can move up and down, therefore, the chain 9 pulls the movable gear 10 to rotate at one end of the chain fixing seat 16, and drives the fixed gear 18 to rotate, so that the chain 9 pulls the tray 7 to ascend and lock at a specified position. This is so that the carriage 6 can still be transported by pulling a further obstacle vehicle. Thereby realizing the purpose that one vehicle can convey two barrier vehicles.
